CAR-VENTILATING SYSTEM.

To all whom it may concern:

Be it known that I, MICHAEL H. SHAN- LEY, a citizen of the United States, residing at Granbury, in the county of Hood and State of Texas, have invented a new and useful Car-Ventilating System, of which the following is a specification.

This invention relates to a system of car ventilation and has for its object to provide means whereby a plentiful supply of fresh air may be directed into a car without the necessity of opening any of the windows thereof, means being employed whereby all dust and other objectionable foreign substances may be removed from the air prior to its admission to the car.

A further object is to provide separate means whereby the entire amount of air admitted to the car may be controlled and whereby the points of admission of air to the car may be varied to suit the wishes of the occupant.

With these and other objects in view the invention consists in certain novel details of construction and combination of parts hereinafter more fully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings,Fig"ure 1 is a side elevation of a car having the present improvements applied thereto, the middle portion of the car being removed. Fig. 2 is a vertical longitudinal section through a car having the present improvements applied thereto, one of the end valves and the inlet tube extending therefrom, being shown in section. Fig. 3 is a vertical transverse section through the car.

Referring to the figures by characters of reference 1 designates the car having a longitudinally extended air-passage in each side wall thereof as indicated at 2, said passage extending over the window frames and being provided, at each end, with an airinlet tube 3 extending beyond the roof of the vestibule. A centrally disposed guide rod 1 is mounted within each of these tubes and the outer end of each tube is preferably flared as indicated at 5 so as to constitute a .seat for a tapered valve 6 which is slidably mounted on the rod 4. A spring 7 is mounted on said rod and is secured at one end thereto while its other end is attached Specification of Letters Patent.

to the valve, this spring serving to hold the valve normally removed from its seat. A cord or other flexible device, such as has been indicated at 8, is secured at one end to the valve and extends longitudinally within the tube 3 and thence over a guide seat 9 and downwardly through an opening in the bottom portion of the tube, this cord being disposed at a point where it can be conven iently reached for the purpose of pulling the valve 6 toward its seat either to partly or to entirely cut off the admission of air to the tube 3. Any suitable means, such a button 10, may be provided for engagement by the cord so that the valve may be held in any position to which it may be adjusted.

Air spaces 11 are formed between the window frames and communicate at their upper ends with the air passage 2, the outer wall of each of these air spaces being formed by a removable panel 12. Downwardly inclined deflecting plates 18 are located within each of the air spaces 11, these plates being arranged in staggered relation and lapping. The lower one of said plates constitutes the bottom of the air space, as indicated at 14: and has a drain pipe 15 extending from it and opening through the bottom of the car. Openings 16 are formed in the inner wall of each air space and constitute outlets for the air contained within the air space, and these openings are designed to be closed entirely or partly, by means of a slide 17 which is mounted on the inner surface of the car wall, there being any suitable means, such as a handle 18, whereby the slide can be readily manipulated.

A cylindrical tank 19 is supported within the car and adjacent the top of each of the side walls thereof, the said tank being provided, above each of the slides 17, with an outlet tube 20 opening into the adjoining air space and provided with a suitable valve 21 whereby the escape of the contents of the tank to the air space may be readily controlled. Each tank may be provided with one or more inlets 22, these inlets being pref erably in the form of funnels extending through the top of the car.

In using the device herein described, the tanks 19 are first filled with water, the valves 21 being of course closed. The cord 8 of the front valve 6 is then released so as to permit the spring 7 of said valve to unseat the valve. Air will therefore pass through the front tube 3 and into the air passage 2 and will then be distributed to various air spaces 11. By opening the valves 21 the water contained within the tanks 19 is permitted to flow through the tubes 20 and into the air spaces 11, this water passing clownwardly along the inclined deflecting plates 13 and dropping from one to the other until it reaches the lowermost plate 14 after which it will pass outward through the drain pipe 15. This water, in passing from one plate to another, forms a sheet of water through which the air mustpass in traveling from the passage 2 to the outlet opening 10, and therefore, it will be seen that when the open ings 16 are uncovered the air escaping through them and into the car will be free of all impurities. The plates 13 and 14: can be readily reached for the purpose of cleaning them, simply by removing the panels 12. These plates may be covered with absorbent cloths, as shown at 23, so that moisture will be retained thereby. It is of course to be understood that the tanks 19 are of suilicient capacities to permit a constantsupply of water to be used for a considerable period. By manipulating either or both of the valves 6 the supply of air to the interiors of the walls can be controlled and, obviously, by manipulating the slides 17, the admission of air to the interior of the car can also be regulat-ed.

Various changes can of course be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as defined in the appended claims.

hat is claimed is y 1. A car having hollow walls, an inlet tube opening into each of said walls, a controlling valve within each of said tubes, said walls having outlet openings for directing air into the car, deflecting plates within the walls and interposed between the inlets and outlets, and valved means within the car for spraying moisture upon the plates.

2. A car having hollow walls, an air inlet tube opening into each wall, said walls having air outlets, lapping deflecting devices within the walls and interposed between the inlets and outlets, a tank, and valved means extending from the tank and in the car for spraying liquid onto the deflecting members.

3. A car having hollow walls, means for supplying air to the interiors of the walls, there being outlet openings within the walls and opening into the interior of the car,

lapping deflecting members arranged within the walls and disposed one above the other, a tank, valved means within'the ear for directing liquid from the tank and discharging it onto the deflecting members, a drain device extending from the lower deflecting member in each wall, and a valve for controlling the supply of air to the interior of each wall.

In testimony that I claim the foregoing as my own, I have hereto atliXed my signature in the presence of two witnesses.
